The year in the gardens

Top to bottom, left to right: Hellebores; Allium 'Purple Sensation'; Paeonies; Heuchera 'Palace Purple' with Erigeron karvinskianus; Acer palmatum 'Sango-Kaku' with Pittosporum tenuifolium 'Golf Ball'; Achillea millefolium 'Cloth of Gold' with penstemons and clematis; Rosa 'Rhapsody in Blue'; Dicksonia antarctica; Salvia 'Amistad'.

It's been an unsettled year for gardening in London, with frequent unseasonal changes in the weather, although nothing like the challenge of last year's three month drought. An icy January gave way to a very muddy February, neither conditions ideal for getting early planting underway. Then came a long dry spring characterised by continued cold nights which inhibited growth in new plants.


Some plants thrived in the conditions: tulips came late, but very strongly once they were in flower; hellebores loved the long start to the year and paeonies were the best they've been for many years across several gardens. Acers suffered in the cold winds (and probably some waterlogging in some specimens) - I was called out to inspect and assess several Acers with withered branches - in some cases affecting as much as half an established plant. Those in sheltered sites in dappled shade seemed to fare the best.

Roses also had a good year, especially climbers heavy with blooms from June onwards. Other summer reliables such as Agapanthus and Hemerocallis had a steady, if not showstopping, year.


As summer gave way to a wet and sometimes windy autumn, leafy ferns came into their own in the damp conditions and trees showed their autumn colours early. Hylotelephiums (formerly sedums), dahlias and the tall Salvias such as 'Amistad' and 'Black and Blue' brought dramatic late colour to many gardens.


As I write this, the Nerines are just coming out, and we have the delicate blooms and sweet vanilla scents of Hamamelis, Sarcococca and Daphne odora to look forward to over winter, along with bright berries and the glossy green leaves of many evergreens.

Planting for a shady rockery


Choosing the planting for this rockery was one of my very first garden design jobs and I always appreciate the opportunity to return to gardens I have helped to create to see how they develop as the plants establish and settle. This planting is two years old now and the plants have matured and grown in an around the rocks. While it's always satisfying when the finished article looks much as you had envisaged it, sometimes plants grow together in unexpected ways and you can get a quite new, unintended but still appealing arrangement. 

 It was completely bare of any vegetation when I took it on, something I now know is quite unusual - a completely blank slate to work with.
Although laid out as a rockery, it faces east and is predominantly shady. Paradoxically the north end is the brighter side, as trees and fencing overshadow it on the southern edge. So the conventional sun-loving alpine plants had to be set aside in favour of leafier shade lovers.


When initially planted up, you can see the distances between plants quite clearly. The positioning of the rocks determined the spacing between plants just as much as allowing for their eventual spread. 

Two years on, and Buddha is sitting atop a wave of grasses, flanked by the two small conifers and the Japanese anemones as a backdrop. Tellima grandiflora provides background vegetation in spring and summer. The colour palette of mostly pinks and purples is designed to be visible from the kitchen window opposite at the far end of the garden.

At this time of year, the sedums form pink cloudy cushions for Buddha, and the Verbena bonariensis will add colour until the first frosts. their seed heads will add structure to the evergreen leaves over winter and then in spring the bed comes alive with bulbs: crocus, dwarf daffodils, chionodoxa, and snowdrops, and then tulips and yellow and gold primulas.

Plants that have done well in this somewhat unpromising environment include Heuchera - the 'Palace Purple' is crowding out 'Ginger Ale' and we will plant more 'Ginger Ale' next year to maintain the balance of light and dark leaves - Euphorbia myrsinites at the brighter end of the bed whose leaves look suitably alpine like, Luzula sylvestris, and the ferns. Tiarella puts on a brave display during the spring and early summer but is barely evident for the  rest of the time, and Alchemilla mollis is beginning to self-seed satisfactorily. My efforts to establish Aubretia have come to nothing so far: too dark and damp, I suspect and I am now looking for something else that will fulfil an Aubretia-like function, ie, tumble over the stones with some bright flowers, which is also better suited to the conditions.

The focal point within the bed was originally to be a single conifer, either a Juniper 'Skyrocket' or J. communis 'Hibernica', or ideally something slower growing. Buddha at the time was sitting rather lonely under a tree nearby and the client suggested moving him to the centre of the new rockery with his two conifer sentinels. He looked at home straightaway, and I swear his face has developed a smile since his move.

We had another serendipitous discovery while preparing the bed for planting. I cut back the ivy covering the fence behind quite dramatically and fund a few straggly and tattered wisteria stems underneath. By clearing a space around them and giving the wisteria more light it has shot up and this year gave us long racemes of blue flowers for a dramatic backdrop to the bed.
